StudyHall is a web and mobile learning platform for structured study and exam preparation. It combines AI assistance, grammar practice, and teacher-led assessments to help students work with complex materials more efficiently. Our client got clear tools for educators to track progress and understanding in one system.

Zuzzle is an online learning tool for organized study of foreign languages and academic disciplines. The product helps students prepare for exams. They have tests, exercises, learning data, and planning tools all in one interface. The Yojji team created this e-learning platform as a scalable system that allows users to schedule daily study activities across desktop and mobile devices, track progress by subject, and examine performance trends.

A matter of design (AMOD) is a web and mobile platform where users can redesign real apartments, manage subscriptions, save ideas, and buy furniture without switching between separate tools. Our task was to design and develop the full product: secure authentication, subscription and payment logic, AI-based room redesign, bookmarking, and e-commerce functionality.

Our Yojji team built Time Machine as an internal time tracking system because existing tools didn’t match our workflow. The web app allows our employees to log hours by project, add weekly comments, and separate billable from non-billable time. Managers got clear visibility into workload and performance. The main focus was on simplicity, so new team members can start tracking time in just a few clicks.
